Abstract

L'invention concerne un système de surveillance de pression de pneu comprenant des capteurs de pression de pneu installés à l'intérieur de pneus de véhicule, un récepteur, un dispositif d'alerte, un dispositif d'entrée/sortie électronique et un dispositif de commande électronique. Le récepteur reçoit des signaux de pression de pneu des capteurs de pression de pneu. Le dispositif d'entrée/sortie électronique fournit une entrée manuelle d'instruction et de données. Le dispositif de commande électronique est configuré pour surveiller une pression de pneu et, en réponse à une pression de pneu de chacun des pneus de véhicule, atteignant une modification d'une première pression de pneu prédéfinie à une seconde pression de pneu prédéfinie, le dispositif d'alerte est mis en œuvre pour alerter une personne modifiant la pression de pneu que la modification a été atteinte. La première pression de pneu prédéfinie correspond à des conditions de conduite sur route enrobée et la seconde pression de pneu prédéfinie correspond à des conditions de conduite hors route.
